The goal of this project is to provide a generator for lexical analyzers of maximum computational efficiency and maximum range of applications. This includes the support for Unicode (UTF8, UTF16, ...) and a large variety of other encodings directly and via nested converters such as ICU(tm) and IConv. Sophisticated buffer handling allows to operate on plain file streams, on sockets, or manually fed buffer content. 'Ready-to-build' examples explain related concepts and facilitate practical applications.
Features
- Support for Unicode and many other character encodings.
- Modes with inheritance relationships and transition rules.
- Sophisticated buffer management.
- Include stacks.
- Customized token classes.
- Template compression for code size reduction.
- Path compression for code size reduction.
- Possibility of indentation based lexical analysis, also called 'off-side rule' (INDENT, DEDENT, NODENT).
- Produces direct coded lexical analyzers.
- Adjustable implicit line and column number counting.
- Introduces DFA Algebra.
- Fuzzy-Matching/Edit Distance, Levenshtein and PseudoDamerau Automata.
- Support for DNA analysis (\RNA and \DNA).

Simply solve complex auth. Easy for devs to set up. Easy for non-devs to use.
Custom auth drains 25% of dev time and risks 62% more breaches, stalling enterprise deals. Frontegg platform delivers a simple login box, seamless authentication (SSO, MFA, passwordless), robust multi-tenancy, and a customizable Admin Portal. Integrate fast with the React SDK, meet compliance needs, and focus on innovation.
